KNOCKDOWN SECTIONAL BOOKCASE.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed June 27, 1906. Serial No. 323,713.

To a/ZZ ulwm, t may concern:

Be it known that I, FRED W. ToBEY, a citizen of the Unit-ed States,residing at Grand Rapids, in the county of Kent and State of Michigan,have linvented certain new and useful Improvements in KnockdownSectional Bookcases; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in knockdown sectional bookcases;and its objectis to provide a structure adapted to be made mainly andsubstantially of wood, which structure will not Warp or spring out ofshape, that can be readily assembled and disassembled, and to providethe same with various new and useful features hereinafter more fullydescribed, and particularly point* ed out in the claims, reference beinghad to the accompanying drawings, in which- Figure 1 is a perspective ofone section of a bookcase embodying my invention as it appears whenassembled; Fig. 2, a plan view of the same; Fig. 3, a vertical sectionof the same on the line 3 3 of Fig. 2 Fig. 4, a transverse section onthe line 4 4. of Figs. 2 and 3 Fig. 5, an elevation of the inner side ofone of the end sections; Fig. 6, a detail in elevation, showing thefastenings connecting the back and ends; Fig, 7, the same in plan view;Fig.

8, a detail showing the coupling-hook in elevation on an enlarged scale,and Fig. 9 a perspective of a l air of coupling-hooks detached.

Like num ers refer to like parts in all of the figures.

The coupling ortions of the shelf members consist of tlie rear member 1and the front member 2, spaced apart and permanently connected by endstrips 3, in which are upper grooves 4 and lower grooves 20. Thesestrips are also provided with recesses 5 opposite the space between theshelf members 1 and 2 to receive the ends of the middle shelf member 10,which latter is secured to a thin bottom plate 9 to receive and supportthe books. Each end section 7 has an upper tongue 6 to engage the groove20 and a lower tongue 22, having a middle recess 5, which tongue engagesthe upper groove 4, and the recess 5a receives the end of the middlemember 10. These tongues and grooves serve to maintain alinement oftheend sections, and

t-he recesses 5 and 5a insure front alinement of the same by engagingthe middle member 10.

11 are coupling-hooks slidable in openings in the end sections andretained therein by screws or studs 25, extending through slottedopenings 24 in the plate portion 26 of said hooks. The outer ends of thchooks are turned in opposite directions at the respective ends of thecase, whereby they interlock and couple adjacent sections to each other.At the exposed end of the case these hooks areslid inward vin therecesses, so that they will not project from the case. The back 12 atits upper'and lower edges engages grooves 13 inthe respective upper andunder sides of the member 1 and at each end is detachably secured to theend sections by means of hooks A1.4, attached to the respective ends ofthe back, and eyes 15, attached to the end sections.

If for any reason it is found desirable to permanently secure a sectionin assembled relation, I provide holes 16 in the end strips 3, throughwhich nails or screws may be inserted in the ends of the end. sections.

17 represents ways or supports for the front or door 8. 18 is ahorizontal groove above said support engaged and traversed by therespective ends of the rod 23, which pivotally supports the front ordoor and carries the same.

21 is a vertical opening to admit the ends of the rod 23 tothe groove 18 when assem# bling the device.

It will be noted that this structure is made almost wholly of wood, andat the same time the parts are so constructed that the device is notlikely to get out of shape and will be easily and readily assembled ortaken apart, as occaslon requires.

What I claim is- 1. In a knockdown sectional bookcase, front and rearvshelf members s aced apart, end strips attached to said memlers andprovided with rooves in their upper and lower sides, a mitFdle shelfmember adapted to be placed between the front and rear members, a plateattached to said middle member, and end sections havinvr tongues ontheir respective ends to enter the said grooves in the end strips.

2. In -a knockdown sectional bookcase, front and rear shelf membersspaced apart,

ICO

`end strips attached to said members and provided with grooves andrecesses, a middle shelf member between said front and rear members andengaging the recesses, and end sections having tongues to engage thegrooves.

3. In a knockdown sectional bookcase, a shelf member having grooves inthe upper and lower sides of its ends and grooves in its rear portion, aback engaging the rear grooves, end sections having tongues on theirrespective ends to engage the said end rooves, and detachable fasteningsconnecting the ends and back.

4. In a knockdown sectional bookcase, front and rear shelf membersspaced apart, the rear member having grooves in its upper and lowersides, end strips attached to said members and havin grooves intheirupper and lower sides an recesses in their inner sides, a backinserted in the rear grooves, end

sections having tongues to engage the grooves in the end strips and arecess in the lower tongue to receive the middle shelf member, a middleshelf member engaging the recesses, and hooks and eyes detachablyconnecting the end sections and back.

5. In a sectional bookcase, hooks horizontally slidable in recesses inthe ends ofthe sections, and adapted to engage corresponding hooks onadjacent sections, and detachably connect the sections end to end.

6. In a sectional bookcase, a hook having a plate portion provided witha slot, flanges on three sides of the 4plate portion, a hook on thefourth side of the same, an end section having a recess in which thehook is slidable, and a screw inserted in the slot and case.

7. In a sectional bookcase, a hook having a plate portion provided witha slot, a hook on the outer edge of the late portion, an end section tothe case an( havin a recess in which the plate is slidable, an a screwinserted in the slot and end section.

In testimony whereof I affix my signature in presence of two witnesses.

FRED W. TOBEY.
